casings for pilings and the like and also t0.v

the means for carrying out the method.

The 0feneral object of the invention is tov form the lower part of the casing first and to add the rest thereof as it sinks by its own weight.

Another object of the invention is to provide a stationary form into which the concrete is poured and out of the lowerend of which the casted part of the easing passes under the action of gravity.

Still another object of the invention is to provide a cutting member upon which the j bottom of the casing rests for facilitating the passage of the casing into the ground, and this member forms the bottom of the form at the beginning of the operation.

This invention also. consistsV in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and lspecifically pointed out in the appended claims.

In describing my invention in detail, referenee will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is a longitudinal sectional view through the "form, the supporting platform and its associated parts, and showing a portion of the casing.

Fig. 2 is a plan view of the parts shown in Fig. 1.

Fig. 3 is a plan view of the casing and showing the arrangement of the cables.

Fig. 4 is a section on approximately the lines 4 4 of Fig. 2, and showing the lower .end of the casing and the manner of forming the foundation therefor.

Fig. 5 is a section on lineY- of Fig. 1. In these views A indicates a circular form which is composed of the outer shell 2 and y the inner shell 3. The upper end of this form is secured to the Vplatform 4 in any suitableimannei'.' "The platform is so madethat the cement can be poured into the upper i Vend of the form.V Thisplatform4 supports the framework 5- to whichthe biocks 6 are secured by the bolts. 7. 'These blocks sup# port-theycables 8 which are arranged'to f5' passfthrough the form. and have "their lower r v ends'connected with the annularrmember 9 vwhichis provided` with thecuttingedge 10.

After theplatform and the form areprop-V erly located the cutting member 9 islowered intol the form and-this member lwill act as a bottom for thegform to support the con- Y crete'. The concrete is then poured into the The upper part ofV the cast is held within the mold Aor formr so as to receive the next cast. placed in the form payed out to permit the finished part of the casing to sink and then a new batch is 'poured into the mold and this is kept up until the casing is of sufficient length.

If the casing should fail to sink under its l own weight, jets of water may be forced around the cutting edge to assist it, this water being forcedinto the pipe or pipes 13 from any suitabley source.

The material for this next cast is then and then the cables are v'form to make thelowerjcast of the casing,v f

9ev i rlhe cables will prevent the cast from slipping out of the form if a very soft spot of ground should be reached which would permit the cast to sink faster thanthe green y concrete at the top is hardening.

It will of course be understood that a pump outfit, indicated generally atB, may be used for pumping out the water Vwithin the casing. v

I form openings in the inner shell of the form and each opening is closed by a pair of doors 14 which are hinged yto angle irons 15, secured to the shell. The adjacent edges' of the doors are provided with recesses for receivingVv the projecting parts of bolts 16 or the like which are adapted to be placed in the concrete. in this way when the cast has hardened and is to be lowered, fthe doors are swung open to permit the bolts to move downwardly with the cast. These bolts may be used for supporting platforms or the like, F or instance, it might be necing and these bolts can beused for sup- Y porting the walls of these chambers.

Fig. 4f shows a structure built around the lower end of the casing for receiving thev foundation for theY same.

It is thought from the foregoing description that the Y advantages (and novel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall within thevscope of the appended claims.

l. A device of the class described comprising a platform, a mold supported by said platform, a cutting member, and controlling cables for regulating the movement ofthe cutting membery and cast` from the mold. l

` 2. A device for forming concrete casings comprising a bottomless mold for receiving the cast, said cast being adapted to pass ,from the mold under iframe, cables supported by the action of gravity and means for controlling the movement of lthe east-from the mol 8. A device for forming concrete casings comprising a bottomless mold, supporting means for the same, means for regulating the movement of the cast from the mold and movable tongues in the innermoldV for permitting projections t0 be inserted in the cast. 1

4. A device of the class described comprising a platform, a mold having its upper end connected with said platform and its lower end open, a framework supported by the platform7 pulley blocks carried by the the said blocks and extending through the mold and a out# ting member connected with the lower ends of the cables, said blocks permitting the cables to be payed out so that the cast and lcutting member may sink under their own weight.
